    hardware: stop using instance cell topology in CPU pinning logic

    Currently we consider the existing topology of the instance NUMA cell when
    deciding on the proper way to fit instance CPUs onto host. This is
    actually wrong after https://review.openstack.org/#/c/198312/. We don't
    need to consider the requested topology in the CPU fitting any more as
    the code that decides on the final CPU topology takes all of this into
    account.

    We still need to expose the topology so that the spawning process can
    use that to calculate the final CPU topology for the instance, but we
    should not consider this information relevant on any of the subsequent
    CPU pinning fit recalculations.
